Existence and multiplicity of solutions for sublinear ordinary differential equations at resonance
Using a $Z_2$ type index theorem, we show the existence and multiplicity of solutions for the sublinear ordinary differential equation $$ \mathcal{L} u(t)=\mu u(t)+W_u(t,u(t)),\quad 0\leq t\leq L $$ with suitable periodic or boundary conditions. Here $\mathcal{L}$ is a linear positive selfadjo...
